Recently, great efforts have been made to use biosensors for the early diagnosis of cancer. Specifically, using a biomarker to detect H2O2 in physiological conditions is of great significance for understanding the signal transduction pathways and achieving early cancer diagnosis. In this work, we report an innovative H2O2 sensor that was fabricated by trimetallic AuPtPd nanocomposites platform on...
Graphene sheets are a sp2-hybridized carbon material that offer extraordinary electrical conductivity and excellent thermal and mechanical properties. They are expected to find use in a wide variety of applications. In this study, a new novel electrocatalyst, a Pb nanowires-Au nanoparticles nanocomposite decorated with reduced graphene oxide (rGO-Pb NWs-Au NPs), was successfully synthesized by an...
A new electrocatalyst, Pt-Ag bimetallic nanoparticles decorated reduced graphene oxide nanocomposite, was successfully synthesized by a facile, eco-friendly and controllable route. The morphological characterization of RGO/Pt-Ag NPs nanocomposite was examined by transmission electron microscopy (TEM), energy-dispersive X-ray spectroscopy (EDX) analyzer, X-ray diffraction (XRD) spectrum, and Fourier...
Dendritic gold nanostructures (AuNDs) were successfully synthesized by one step electrodeposition on reduced graphene oxide (rGO) functionalized by a globular protein, β-lactoglobulin (BLG), for the first time. Owing to its sulfhydryl groups, water-soluble BLG–rGO provided a superb platform for the growth of AuNDs. Scanning electron microscopy, Raman spectroscopy and X-ray spectroscopy analysis were...
